ABSTRACT
Through relay selection and power allocation can achieve the purpose of improving the performance of Two-way relay system. This paper considered the probability of outage, proposed a Relay Selection Strategy based on Probability of Outage (RSSPO) in Two-way AF relay system. In order to enhance the sum-rate of Two-way relay system, a new Power Allocation Scheme based on Convex Optimization (PASCO) is proposed when total power is limited. Simulation result shows that both of the strategies can enhance the performance of the networks.
